COOLING SYSTEM FOR MOTORS.

Application filed May 31,

T0 aZZ whom it may concern:

Be it known that I, O'rro M. LUNDnNn, a citizen of the United States,residing at Flint, in the county of Genesee and State of Michigan, haveinvented new and useful Improvements in Cooling Systems for Motors, ofwhich the following is a specification.

This invention relates to cooling-means for internal combustion engines,the prin cipal objectof the invention being to provide means forintroducing air into the water circulating system of the motor to coolthe water and also to quicken the circulation thereof.

Another object of the invention is to provide an air pumpfor supplyingthe air to the circulating system with means for actuating the same fromthe motor.

A further object of the invention is to provide an injector which isconnected with the pump and is so arranged in the circulating systemthat the air will be injected in the same direction as the water iscirculating.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claim. 1 i

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is a diagrammatic view showing the invention in use.

Figure 2 is an enlarged sectional view of the air pump.

Figure 3 is a section on line 33 of Figure 2. I

Figure 4c is an enlarged sectional view showing the arrangement of theinjector in the circulating system.

Figure 5 is adetail view of the injector.

In these views 1 indicates the internal combustion motor and 2 indicatesthe r'adia-' tor which is connected with the water jacket of the motorby the pipes 3 and 4c.

In carrying out my invention I inject a supply of air in the circulatingsystem to cool the water and to quicken its circulation and I do this byinserting an injector 5 in the pipe 3, the outlet end of which isprovided with a plurality of holes 6 so that 1921. Serial No. 473,842.

there are several, streams of air injected into the water. The injectoris so arranged as to deliver the air in the same direction the water isflowing so as to quicken the circulation of the same as well as cool it.An elbow 7 is connected with the injector and passes through the pipe 3,said elbow being provided with a suitable gland to make" a I water tightjoint. A pipeline 8 is connected with the elbow andthis pipeline leadsto an air pump 9 which consists of the base 10 in which the crank shaft11 is journaled, the cylinders 12 suitably connected with the base andcontaining the pistons 13 which are connected with the crank shaft. Eachcylinder is connected with. the manifold 14 by a pipe 15 in which islocated a check valve 16. Manifold 14 is connected with the pipe 8. Thecrank shaft is connected by a train of gearing 17 with the fly wheel orother movable part of the motor so that when the motor is operating thepump will be actuated to supply compressed air to the injector. Thegears may be of the toothed type or of the friction type as desired andsuitable means may be provided forrendering them inactive.

A check valvev in order to prevent water from backing up in the linewhen the pumpis not operated.

It will thus be seen that a supply of air 18 is placed in the line 8 lis forced into the circulating system while the motor is operating sothat the water is prevented from being heated to a high degree and itsflow through the water jacket of the motor is qui'ckened.

It is thought from the foregoing decription that the advantages andnovel features of my invention will be readily apparent I desire it tobe understood that I may make changes in the construction and in thecombination and arrangement of the several parts, provided that suchchanges fall within the scope of the appended claim.

What I claim is In an internal combustion engine having a watercirculation cooling system comprising an air pump for supplyingcompressed air through an injector andv into the water circulatingsystem, a nozzle having an enlarged extremity, and a perforated facethrough which the force of air is sprayed in the circulating directionof the water.
